    • On-field phenotypic evaluation of sunflower populations for broad-spectrum resistance to Verticillium leaf mottle and wilt 

      Montecchia, Juan Francisco; Fass, Monica Irina; Cerrudo, Ignacio; Quiroz, Facundo Jose; Nicosia, Salvador Maria; Maringolo, Carla Andrea; Di Rienzo, Julio A.; Troglia, Carolina Beatriz; Hopp, Horacio Esteban; Escande, Alberto; Gonzalez, Julio Horacio; Alvarez, Daniel; Heinz, Ruth Amelia; Lia, Veronica Viviana; Paniego, Norma Beatriz (Springer Nature, 2021-06)
      Sunflower Verticillium Wilt and Leaf Mottle (SVW), caused by Verticillium dahliae (Kleb.; Vd), is a soil-borne disease affecting sunflower worldwide. A single dominant locus, known as V1, was formerly effective in controlling ...

    • Peculiarities of the Transformation of Asteraceae Family Species: The Cases of Sunflower and Lettuce 

      Darqui, Flavia Soledad; Radonic, Laura Mabel; Beracochea, Valeria Cecilia; Hopp, Horacio Esteban; Lopez Bilbao, Marisa Gisela (Frontiers Publishing, 2021-11)
      The Asteraceae family is the largest and most diversified family of the Angiosperms, characterized by the presence of numerous clustered inflorescences, which have the appearance of a single compound flower. It is estimated ...

    • Phenotyping sunflower genetic resources for Sclerotinia head rot response: assessing variability for disease resistance breeding 

      Filippi, Carla Valeria; Zubrzycki, Jeremias Enrique; Di Rienzo, Julio A.; Quiroz, Facundo Jose; Fusari, Corina Mariana; Alvarez, Daniel; Maringolo, Carla Andrea; Cordes, Diego Darío; Escande, Alberto; Hopp, Horacio Esteban; Heinz, Ruth Amelia; Lia, Veronica Viviana; Paniego, Norma Beatriz (The American Phytopathological Society, 2017-11)
      Sclerotinia head rot (SHR) is one of the most serious constraints to sunflower (Helianthus annuus L. var. macrocarpus) production worldwide. Here, we evaluated the response to SHR in a sunflower inbred panel from a large ...

    • Population structure and genetic diversity characterization of a sunflower association mapping population using SSR and SNP markers 

      Filippi, Carla Valeria; Aguirre, Natalia Cristina; Rivas, Juan Gabriel; Zubrzycki, Jeremias Enrique; Puebla, Andrea Fabiana; Cordes, Diego Darío; Moreno, Maria Valeria; Fusari, Corina Mariana; Alvarez, Daniel; Heinz, Ruth Amelia; Hopp, Horacio Esteban; Paniego, Norma Beatriz; Lia, Veronica Viviana (BMC, 2015-02)
      Background: Argentina has a long tradition of sunflower breeding, and its germplasm is a valuable genetic resource worldwide. However, knowledge of the genetic constitution and variability levels of the Argentinean germplasm ...

    • Sunflower germin-like protein HaGLP1 promotes ROS accumulation and enhances protection against fungal pathogens in transgenic Arabidopsis thaliana 

      Beracochea, Valeria Cecilia; Almasia, Natalia Ines; Peluffo, Lucila; Nahirñak, Vanesa; Hopp, Horacio Esteban; Paniego, Norma Beatriz; Heinz, Ruth Amelia; Vazquez Rovere, Cecilia; Lia, Veronica Viviana (Springer, 2015-10)
      Germin-like proteins (GLPs) are a large, diverse and ubiquitous family of plant glycoproteins belonging to the Cupin super family. These proteins have been widely studied because of their diverse roles in important plant ...

    • Sunflower leaf senescence : a complex genetic process with economic impact on crop production 

      Moschen, Sebastian Nicolas; López Gialdi, Agustín I.; Paniego, Norma Beatriz; Fernandez, Paula del Carmen; Heinz, Ruth Amelia (2017)
      Leaf senescence is a complex process controlled by multiple genetic and environmental variables. In different crops, a delay in leaf senescence has an important impact on grain yield trough the maintenance of the photosynthetic ...

    • Sunflower: a potential fructan-bearing crop? 

      Martínez-Noël, Giselle M. A.; Dosio, Guillermo; Puebla, Andrea Fabiana; Insani, Ester Marina; Tognetti, Jorge (2015-10)
      Grain filling in sunflower (Helianthus annuus L.) mainly depends on actual photosynthesis, being the contribution of stored reserves in stems (sucrose, hexoses, and starch) rather low. Drought periods during grain filling ...

    • Transcriptomic Analysis Reveals a Differential Gene Expression Profile Between Two Sunflower Inbred Lines with Different Ability to Tolerate Water Stress 

      Escalante, Maximiliano; Vigliocco, Ana Edit; Moschen, Sebastian Nicolas; Fernandez, Paula Del Carmen; Heinz, Ruth Amelia; Garcia-Garcia, Francisco; Di Rienzo, Julio A.; Andrade, Andrea; Alemano, Sergio Gabriel (Springer, 2020-01)
      Although sunflower (Helianthus annuus L.) is categorized as a medium drought-sensitive crop, in a changing climate scenario and/or with the onset of early droughts, the crop may be affected by water stress. This study ...

    • Unveiling the genetic basis of Sclerotinia head rot resistance in sunflower 

      Filippi, Carla Valeria; Zubrzycki, Jeremias Enrique; Di Rienzo, Julio Alejandro; Quiroz, Facundo Jose; Puebla, Andrea Fabiana; Alvarez, Daniel; Maringolo, Carla Andrea; Escande, Alberto; Hopp, Horacio Esteban; Heinz, Ruth Amelia; Paniego, Norma Beatriz; Lia, Veronica Viviana (BMC, 2020-07)
      Background: Sclerotinia sclerotiorum is a necrotrophic fungus that causes Sclerotinia head rot (SHR) in sunflower, with epidemics leading to severe yield losses. In this work, we present an association mapping (AM) approach ...
